SPECIFICATION forming part of Letters Patent No. 357,619, dated February 15, 1887. Application tiled September 1'0, 1886. Serial No. M3246. (No model.)

To a/ZZ whom it may concern-.-

Be it known that I, FRANK G. MIDDLE- KAUFF, a citizen of the United States, residing at Forreston, in the county of Ogle and State of Illinois, have invented certain new and useful Improvements in SheafCarriers,

' which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part thereof, wherein- Figure lis a perspective of a portion of a harvester-frame having my improved sheafcarrier attached thereto, the point of view being from the rear outer corner. Fig. 2 is Va side elevation of my sheaf-carrier, shown in full lines in the position of dumping, and in dotted lines in the position to receive the sheaves. Figs. 3 and 4t are side elevations, on a reduced scale, showing slightlymodified forms of my device for dumping the carrier.

A and A2 are, respectively,the front and rear bars of the harvester-frame.

B is the sh caf-carrier.

C' is a cranked rock-shaft journaled on the rear bar, A,having the crank-arm C10 and the crank-wrist C extending stubbleward at right angles to the direction of travel.

. C2 is a similarly-cranked rock-shaft journaled o n the front bar, having a similar crankarm, 02, and the crank-wrist C21 parallel with the crank-Wrist Ou. Upon the two crankwrists C and C11 the sheaf-carrier B is supported, the wrists being journaled on the lower side thereof. The rock-shaft C is further provided,at its inner end, with the crank-arm C12, and to the same'there is connected the link E, which extends upward in any direction necessary to bring it in convenient reach of the operator.

4o journaled on the carrier nearer together than their respective shafts C and G2 are journaled on the harvester-frame, so that the crank-arms O1 and C20 converge from the shafts to the wrists.

The operation of this device is as follows: When the sheaf-carrier is in the position shown in Fig. 1, and in dotted lines in Fig. 2, it is substantially horizontal and at the proper elevation to receive the sheaves from the bindertable F. When it has been sufficiently loaded, the operator will rock the shaft C by pulling the link E, thereby throwing the crank-arm The crank-wrists Cu and C21 are- C1 downward toward a horizontal position, thus carrying the rear end of the sheaf-carriei-,which is supported on the crank-wrist Cu, downward to the position shown in full lines in Fig. 2. In causing this motion of the rear end,thecarrier is carried longitudinally forward, causing the crank-arm C2", upon whose wrist C21 the forward end of the carrier is journaled,to move forward from the first position, marked 1, (shown in dotted lines in Fig. 2,) to the second position, marked 2 in dotted lines, and as the crank-arm ,O10 rocks still farther over to the horizontal position the forward end of the carrier returns rearward until the crank-arm C20 is substantially vertical, as shown in full lines in Fig. 2, when the crank-arm O10 becomes horizontal. Thus, while the rear end of the carrier, controlled by the crank-arm C1", is moved continuously downward and forward, the rearend, supported and controlled in its motion by the crank-arm 01,without materially changing its elevation, has movedfirstforward and then rearward, so that the carrier, by means ofthe cooperation ofthe two cranked supports, is caused to assume an inclined position, and thereby to discharge its contents.

It will be obvious that the crank-arms might be bent downward,instead of upward, from the shafts, respectively, if the bars upon which said shafts are journaled were high enough to make it desirable to so locate the carrier, as shown in Fig. 3. In that case the tilting of the carrier would be effected by raising one end by rocking the shaft, as described,and the shaft so rocked, in order that the carriershould be dumped,would be the forward instead ofthe rear shaft.

lt will also be obvious that to sustain the end wh ose elevation is substantially unchanged in tilting, any fixed support over which the carrier might reciprocate could be substituted for the rocking support afforded by the crankshaft O2. Such substitution is illustrated in Fig. 4, where the rod C3 is rigid with the harvester-frame and,protrudingstubbleward,supportsl one end of the sheafcarrier,which is allowed to rock and slide over it, as compelled by the movement of the actuating crank-shaft G1".

I claim- 1. In combination with the harvester-frame and the sheaf-carrier, a support for one end of IOG the carrier, pivoted thereto and to the harvester-frame7 said pivots being horizontal and at right angles to the direction of travel, and a pivotal support for the other end of the carrier, upon which the salne may rock and move longitudinally as the carrier is rocked upon the other support, substantially as set forth.

2. In combination with the harvester-frame, a horizontal rock-shaft journaled thereon at right angles to the direction of travel,and having a crank-arm, a sheaf-carrier journaled at one end on the crank-wrist-,and a support for the other end of the carrier, upon which said carrier rocks and moves longitudinally, and means, substantially as described, for rocking the rock-shaft to carry its crank-arm toward a horizontal position, substantially as set forth. 3. In combination with the'harvestenframe and the sheaf-earrier, supports for the two ends of the carrier, pivoted thereto and to the harvester-fra1ne, the pivots of said supports on the frame being farther apart than their pivots on the carrier, substantially as set forth.

4. In combination with the harvester-frame, two horizontal rock-shafts journaled thereon at right angles to the direction of travel and provided with crank-ar1nsand the sheaf-carrier journaled on the wrists of said crankarms, the journal-bearings of the shafts on the harvester-frame being farther apart than the bearings of the wrists on the carrier, and means, substantially as set forth, for making one ofthe shafts to carry its crank-arms toward a horizontal position.
